Document Classes ⇒ [Beamer] Custom headline in split outer theme

[kliput]

Hello!

I want to make some changes in headline navigation (sections and subsections navigation) in split theme. I've tried to add this to my document to override default style:

Code: Select all

\setbeamertemplate{headline}
{%
  \leavevmode%
  \@tempdimb=2.4375ex%
	\@beamer@sectionmax=2
	\@beamer@subsectionmax=2
  \ifnum\beamer@subsectionmax<\beamer@sectionmax%
    \multiply\@tempdimb by\beamer@sectionmax%
  \else%
    \multiply\@tempdimb by\beamer@subsectionmax%
  \fi%
  \ifdim\@tempdimb>0pt%
    \advance\@tempdimb by 1.125ex%
    \begin{beamercolorbox}[wd=.5\paperwidth,ht=\@tempdimb]{section in head/foot}%
      \vbox to\@tempdimb{\vfil\insertsectionnavigation{.5\paperwidth}\vfil}%
    \end{beamercolorbox}%
    \begin{beamercolorbox}[wd=.5\paperwidth,ht=\@tempdimb]{subsection in head/foot}%
      \vbox to\@tempdimb{\vfil\insertsubsectionnavigation{.5\paperwidth}\vfil}%
    \end{beamercolorbox}%
  \fi%
}

This code is similiar to code in beamerouterthemesplit.sty, but without "compressed mode" code.

When I try to compile it, I get an error:

Code: Select all

! Undefined control sequence.
\beamer@@tmpl@headline ...ionmax=2 \ifnum \beamer
                                                  @subsectionmax<\beamer @ se...

What I'm doing wrong? When I'm trying to copy whole content of "beamerouterthemesplit.sty" to another file (ex. "beamerouterthememytheme.sty"), and do some modifications, it doesn't work too.

Thanks in advance for help!

PS. Sorry for my mistakes in English, I'm not native speaker.

Hi,

the code that you are trying to modify contains the special charecter @. To handle this character appropriately in .tex files you should enclose the code using

Code: Select all

\makeatletter
...(code)...
\makeatother

Thank You very much! It works.

Also, I've tried to move whole style definitions to another file in my working directory (ex. "beamerthememystyle.sty"), and it works too, without code You wrote. Strange... but earlier I've used /useoutertheme in my theme file, maybe there was a problem.
